Generalized random energy model. (English) Zbl 1124.82008
The authors apply large deviation methods to obtain the free energy and some further results for the GREM (Generalized Random Energy Models), following mainly the approach recently used by Dorlas and coworkers.
There have been a number of other recent studies of such models, with more detailed results, in particular by A. Bovier and I. Kurkova [Commun. Math. Phys. 263, No. 2, 535–552 (2006; Zbl 1104.82027)], as for example are described in Bovier’s recent book. Most of those are worked out for models with Gaussian randomness. Here the authors also include non-Gaussian disorder, as was earlier done by for example Eisele.
